MACHINE FOR MAKING ROOFING- ELEMENTS.

Specification of Letters Patent.

Patented Sept. 30, 1919.

Application flle'd December 27, 1915. Serial No. 68,660.

To all whom it may concern.

Be it known that I, FREDERICK C. Ovrm- BURY, a citizen of the United States, residing at Hillsdale, in the county ofv Bergen a. and State of New Jersey, have mvented new and useful Improvements in Machines for Making Roofing Elements, of which the following is a specification.

This invention has relation to machines for making roofin elements, and has for its object to provi e a machine for making what I term shingle strips, 11. 6., strips of sheet roofing material provided with tabs or projections of. any desired configuration,

which, when the strips are laid in overlapping relation, present the appearance of separate shingles or tiles.

0n the accompanying drawings,"-

Figure 1 represents in plan view a ma- '1 chine embodying the invention;

. Fig. 2 represents a longitudinal section through the machine on the line 2-2 of T igj 3 shows a sheet of roofing material and a shingle strip which has been severed therefrem; and p Figs. 4, 5 and 6 aresectional views illustrating the feeding and the severing of the sheet into strips.

The machine is particularly adapted for operation upon sheet roofing material comprising one or more layers of felt or analogous fibrous material saturated or impreg- -nated with a suitable waterproofing compound such as asphalt, pitch or the like, and coated with a relatively hard pitch or asphalt, and surfaced if desired, with a layer of crushed mineral material or grit more or less embedded in the coating before it sets or hardens.

Referring to the drawings, the machine as shown may conveniently comprise side standards 10, 11, suitably connected and braced and of any suitable design. At one end the machine has a pair of feed rolls 12, 13, connected together by the gears 14;, 15, to one of which power is applied to cause their rotation as will presently be explained in detail. The rolls extend across the machine and are of sufiicient width for the sheet to be fed thereby.

At the other end of the machines are the coacting cutting rolls or cylinders, of which of the bed roll 16, in such close is shown as zigzarr, so that, when the strip a is severed it will have along its edge a series of angular projections b. The two blades may be the same, or they may vary in shape, so that the tab on the two longitudinal edges of each. strip will have a different contour. These blades are inserted and rigidly held in the. grooves formed in the roll 17, and their edges are concentric with said roll, so as tangentially to engage the bed roll 16.

The roll 16 not only cooperates with the cutters in severing the strips, but it also serves in feeding the end of the sheet 0 of roofing material. To this end, I employ an additional feed roll 19, located in the rear roximity thereto as to cause them to grip t e end of the sheet. The roll 19 and the rolls 12, 13, 16 anl 17 are all journaled in suitable bearings on the side frames 10 and 11. The axis of the roll 19 is slightly below a plane tangential to the rolls 15 and 16, so that the .sheet is compelled to travel a somewhat tortuous path in passing from the feed rolls to the cutting rolls. I employ therefore a table 20 extending from one side frame to the other, the front end of which is bent downwardly and forwardly to guide the? sheet to the under side of the feed roll 19.

In. operation, as shown in Figs. 4, 5 and 6, the end of the sheet is engaged by the rolls 16 and 19, and is fed thereby to posltion to be engaged by the cutters 18. As one cutter in its revolution cuts off a strip from the extremity of the sheet, the end of said sheet remains in the grip of the feed and bed rolls and is fed to position to be engaged by the next cutter.

The rolls 12, 13,16 and 19, and the cutters 18, all travel at the same peripheral speed and may be connected by any suitable gearing to secure thisresult. For example, I may employ the following train of powertransmitting mechanism :a main shaft 220 driven by a belt 21 and pulley 22, a gear 23 on saidshaft, a gear 24: on the bed roll shaft intermeshing with gear 23, a gear 25 on the cutter roll shaft intermeshing with gear 24,

a gear 26 on the shaft of the feed roll 19 drlven by gear 24, and idler gears 27, 28, driven by gear 26 and driving gear 15 on the roll 13. The gear 27 is secured on a shaft 29 on the other end of which is a sprocket wheel 30 for transmitting power by the chain 31 to a sprocket 32 on a drum shaft 33. The shaft 33 and a parallel shaft 34, on a lower plane, operate an inclined endless belt 35, located to receive and carry away from the machine the severed hingle trips.

The sheet to be cut into strips may be drawn directly from the coating rolls; but, if in roll'form, the roll of material as at d may be -journaled on a frame 40 as shown in Fig. 2.

Itwill be observed that each cutter 18 is continuous from end o end, so as completely to sever the strip from the end of the sheet, said cutter being in total length not less than the width of the sheet. I refer to each blade as a zigzag blade to distinguish it from one which would cut the sheet on a straight or unbroken transverse line, meaning to m- 'clude thereby any transversely arranged blade which will leave tabs or projections on the longitudinal ed e of the strip.

Having thus exp ained the nature. of my said invention and described a We, of makand using the same, althoug without attempting to set forth all of the forms in the sheet from which it may be made or all of the modes of 7 its use, what I claim is:

1. A machine for cutting shingle strips having tabs 0r projections from a sheet of roofing material, comprising a bed roll, a cooperating cutting roll, said cutting roll having a zigzag blade extending longitudinally of the periphery thereof, so as to sever the sheet transversely from edge to edge thereof and form the described strip, a feed roll cooperating with said bed roll for feeding rolls, the cutting rolls comprising a smooth M cylindrical bed roll and a cylinder having 7 one ormore zigza blades extending from end to end thereo in combination with a supplemental feed roll consisting of a smooth cylinder arranged to cooperate with said bed roll and having its axis located in a plane below and parallel to a plane tangential to the first-mentioned feed rolls and cutting'rolls, and a table arranged to guide m'ental feed roll. v

In testimony whereof I have afiixed my signature.
